Codi ran up from the backyard to see what was happening but as he was turning a corner near Roselyn’s building, there was a loud bang.

Butane gas canisters that had been stored on a shelf outside the house had begun overheating and exploding.

Despite this loud explosion, Codi kept on going …

“I ran into get her out and grabbed her before she catched (sic) fire,” Codi said.

Roselyn was startled into action.

“Codi came in and said ‘we’ve got to get out’ and that’s when the explosion happened,” Roselyn said.

This second explosion smashed a window on the side of the verandah near where they were.

After he got Roselyn out of the building, Codi rushed back in to get her walker (“because she can’t walk without it”).

“Another bang happened and I felt the ground rumble like an earthquake,” Codi said.

Roselyn then managed to ring Triple 0 and the Fire Brigade were quickly on the scene.

Seven butane gas canisters exploded during the emergency.

Codi’s proud mum, Bunya Nut Cafe owner Evelyn Green, said the explosions were so loud people heard them in town.

It has been a tough time for Evelyn and Roselyn lately. The sisters lost their father Jim Wilson just three weeks ago.

Evelyn now thinks that Jim must have been watching out for family from above …

If Codi hadn’t spotted the smoke, and if the canisters had exploded at a different time, there could well have been a tragedy.

As it is, the fire scorched an external wall of the building, damaged some windows and charred a roof beam.

[UPDATED: An earlier version of this report included the fact a QFES spokesman told southburnett.com.au on Sunday evening it was believed the fire had started in an air-conditioning unit. The family has since contacted us to say this is definitely not the case, and the cause is unknown]
